Once they start turning bad....they don't recover. At least that's my experience.

It's the same with my expert opinion on evergreens = brown does not turn green. Conifers are not deciduous except for one family, the tamarack. It does lose it's needles each year and regrow new ones every year. Also the dawn redwood...it is a member of the larch family...tamarack.

Succulents are not for me. LOL! I live in the desert! But not the sandy desert, the high desert. I can make sagebrush live, but not cactus!
